Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, and particularly relates to a heat pipe finned heat exchanger. Background Art

[0002] The finned heat exchanger is a high-efficiency heat exchanger in the shell-and-tube heat exchanger. This type of heat exchanger mainly uses the fins installed on the outer wall of the heat exchange tubes to increase the heat exchange area, and obtains forced heat exchange in the form of turbulent flow of the heat exchange medium, thereby effectively improving the heat exchange efficiency. This effective structure has been widely used in the industry, and such products have made contributions to energy conservation and emission reduction in the actual use of supporting users.

[0003] However, since the gas outside the heat exchanger will bring dust during the flow process, and since condensed water will be generated during the heat exchange process, the dust is easily attached to the surface of the heat exchanger. After long-term use, it is easy to affect the heat exchange effect of the heat exchanger. In the prior art, usually the heat exchanger is disassembled and cleaned, but this method not only has low efficiency, but also has high cleaning costs. In addition, multiple disassembly and installation are also likely to cause leakage of the heat exchanger, which will bring unnecessary trouble to users.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a heat pipe finned heat exchanger.

[0005] The information disclosed in this background art section is only for increasing the understanding of the overall background of the utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art.

Detailed implementation manners

[0033] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0034] As Figures 1 to 10 shown, a heat pipe finned heat exchanger in an embodiment of the present utility model includes: a fixed protection frame 1 and a cleaning mechanism 2.

[0035] As Figures 1 to 2As shown in the figure, multiple heat exchange conveying pipes 101 are installed inside the fixed protection frame 1 for conveying hot water for heat exchange. Heat exchange fins 102 are installed on the heat exchange conveying pipes 101 to increase the heat exchange area and thus improve the heat exchange efficiency. Connecting elbows 103 are fixedly connected between multiple heat exchange conveying pipes 101, enabling multiple heat exchange conveying pipes 101 to be connected and facilitating the circulation of hot water for heat exchange.

[0036] As Figures 1 to 3 shown in the figure, a liquid inlet pipe 104 and a liquid outlet pipe 105 are installed on the fixed protection frame 1. The liquid inlet pipe 104 and the liquid outlet pipe 105 are respectively fixedly connected to one end of a pair of heat exchange conveying pipes 101. The liquid inlet pipe 104 and the liquid outlet pipe 105 are used to input and output hot water for heat exchange, facilitating the circulation of hot water for heat exchange. A plurality of sewage pipes 106 are installed on one side of the fixed protection frame 1 for discharging the cleaned sewage.

[0037] As Figures 8 to 9 shown in the figure, a plurality of limiting sliding grooves are drilled on the fixed protection frame 1 to provide space and track for the sliding of the limiting sliding block 107. A sliding guide rail 108 is fixed on the side wall of the limiting sliding groove to support and limit the limiting sliding block 107, making it difficult for the limiting sliding block 107 to skew during sliding, and thus ensuring the track for the movement of the sliding support frame 204. The limiting sliding block 107 is slidably arranged on the sliding guide rail 108 to support the sliding support frame 204, making it difficult for the sliding support frame 204 to fall off.

[0038] Specifically, a fixed spring 109 is fixedly connected between the limiting sliding block 107 and the fixed protection frame 1 to tension the limiting sliding block 107 and the sliding support frame 204, so that the device is not prone to shaking, and thus during the cleaning process, the cleaning water is not prone to leakage.

[0039] As Figures 1 to 6 shown in the figure, the cleaning mechanism 2 is installed on the fixed protection frame 1. The cleaning mechanism 2 includes a plurality of fixed shielding plates 201 for assisting the sliding cover plate 202 to cover both sides of the fixed protection frame 1, so that the cleaning water is not prone to splashing. The plurality of fixed shielding plates 201 are respectively installed on both sides of the fixed protection frame 1. A sliding cover plate 202 is slidably connected to the fixed shielding plate 201 to play a plugging role and facilitate the cleaning of the heat exchange conveying pipes 101 and the heat exchange fins 102. A plurality of cleaning spray holes 203 are drilled on the side of the sliding cover plate 202 close to the heat exchange conveying pipes 101 for spraying the cleaning water, so as to be able to take away the dust on the heat exchange conveying pipes 101 and the heat exchange fins 102 and achieve the cleaning effect. The plurality of cleaning spray holes 203 are arranged with different orientation angles.

[0040] As Figures 1 to 6As shown, a plurality of sliding support frames 204 are also fixed on the fixed protection frame 1, which are used to drive the linkage pipe 214 and the connection frame 210 to slide, so as to facilitate the staff to drive a plurality of sliding covers 202 to move simultaneously. One end of the sliding support frame 204 is equipped with a threaded joint 205 for connecting an external cleaning pipe to facilitate the delivery of cleaning water.

[0041] As Figures 1 to 6 shown, a support square pipe 206 is slidably arranged in the fixed baffle 201. The support square pipe 206 is fixedly connected to one end of the sliding cover 202 arranged in the fixed baffle 201, which is used to support the sliding cover 202, so that the sliding cover 202 is not easily detached, and it also has the function of driving the cleaning spray holes 203 to slide. A water delivery hole 207 is drilled on the support square pipe 206 for the flow of cleaning water, so that the cleaning water can enter the sliding cover 202 and then be sprayed out from the cleaning spray holes 203.

[0042] As Figures 1 to 10 shown, a clamping groove 208 is drilled at one end of the fixed baffle 201 away from the sliding cover 202 for the insertion of one side of the sliding cover 202, so that the cleaning water is not easily leaked during the cleaning process. A pair of sliding cavities 209 are also drilled on the fixed baffle 201 for the sliding of the connection frame 210, so that the movement of the connection frame 210 is not easily affected.

[0043] Specifically, a pair of connection frames 210 are fixed on the support square pipe 206, which are used to support and drive the support square pipe 206 to slide and also have the function of delivering cleaning water. The connection frame 210 is arranged in communication with the support square pipe 206 to facilitate the flow of cleaning water. A linkage pipe 214 is fixedly connected between the connection frame 210 and the sliding support frame 204, which is used to drive the movement of the connection frame 210 and can deliver the cleaning water into the connection frame 210.

[0044] As Figures 1 to 7 shown, a pair of side strip plates 211 are fixed on the fixed protection frame 1. Grooves matching the sliding cover 202 are drilled on the side strip plates 211 for assisting the insertion of the sliding cover 202, so that the cleaning water is not easily leaked during cleaning.

[0045] Among them, one end of the sliding support frame 204 away from the threaded joint 205 is fixedly connected with a fixed side plate 212. A fixed bolt 213 is threadedly connected to the fixed side plate 212 and is used to press tightly against the fixed protection frame 1, so that the sliding support frame 204 is not easily moved anymore, and thus the cleaning process is not easily shaken and loosened, and the cleaning water is not easily leaked.

[0046] During specific use, first connect the external cleaning pipe to the threaded joint 205, and then slide the sliding support frame 204 to drive the sliding support frame 204 to drive multiple linkage pipes 214 and the connection frame 210. Then, drive the sliding cover plate 202 to slide through the connection frame 210, so that the sliding cover plate 202 can move out of the fixed shielding plate 201. Then, clamp one side of the sliding cover plate 202 in the card slot 208 on the other fixed shielding plate 201 to achieve the effect of blocking both sides of the fixed protection frame 1. Then, rotate the fixed bolt 213 so that the fixed bolt 213 can be tightened against the fixed protection frame 1 to fix the sliding support frame 204, and further fix the sliding cover plate 202.

[0047] Then, convey clean water into the sliding support frame 204 through the cleaning pipe, and then convey it into the support square pipe 206 through the linkage pipe 214 and the connection frame 210. Finally, after the clean water enters the sliding cover plate 202, it is sprayed out through multiple cleaning spray holes 203. The sprayed clean water will impact on the heat exchange conveying pipe 101 and the heat exchange fins 102, so that the dust on the heat exchange conveying pipe 101 and the heat exchange fins 102 is washed down, and the cleaning water will be discharged through the sewage pipe 106. After the cleaning is completed, the sliding cover plate 202 is retracted into the fixed shielding plate 201, which is convenient for the flow of gas.
